Having problems with the JPA Hibernate Tools Eclipse plugin

I'm trying to create a JPA based hibernate console configuration in Eclipse, but I keep getting the following error when I try to use the console configuration :

Code:

org.hibernate.console.HibernateConsoleRuntimeException: Could not load JPA Configuration
  org.hibernate.console.HibernateConsoleRuntimeException: Could not create JPA based Configuration
    org.hibernate.console.HibernateConsoleRuntimeException: Could not create JPA based Configuration
    java.lang.reflect.InvocationTargetException: <no message>
    javax.persistence.PersistenceException: org.hibernate.MappingException: Could not parse mapping document in input stream
    org.hibernate.MappingException: Could not parse mapping document in input stream
    org.dom4j.DocumentException: Error on line -1 of document  : Premature end of file. Nested exception: Premature end of file.

Here is the persistence.xml file I'm using :

Code:

<?xml version='1.0' encoding='utf-8'?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      <properties>

      </properties>
   </persistence-unit>   
   
</persistence>

Is there something simple I'm missing here? I know that it's finding my persistence.xml in the classpath, because if I enter invalid tags it gives me a parse exception.

I'm using hibernate-tools 3.2 beta9 with the latest JBossIDE.

Any help would be greatly appreciated.

hmm...weeird error. please report in jira since I in any case want to improve that not really usefull error message: "Could not parse mapping document in input stream" ...what document ? :)

When that is said, please check if you got caught by a bug where the tooling automatically add all hbm.xml's it finds to the Mappings tab even though you are using JPA and hence it is not needed.

If yes; try and remove all of them and try again.

Here's a little more information that may or may not be useful :

The window that the error pops up in is titled 'Lazy tree error' with the top error being 'Error while fetching children'.

I looked in my mappings tab, and none of the .hbm.xml files are listed.

Also, I'm assuming that when I'm in the Console Configuration screen, and after I check JPA (jdk 1.5+), that the only other information I need to supply is the name of the persistence Unit I want to use.

Let me know if you still want me to open a Jira ticket on this issue.

I'm hoping that the additional information from the error window might help to track down what's happening.

no unfortunately not.

the "lazy tree error" just hints when it occurs (namely when you expand the node).

for some reason Hibernate EntityManager finds something it wants to read and opens an inputstream that results in -1 bytes ;(

can you try and minimize your project the simplest possible and still trigger the error? if that is possbile then attaching it to a jira case would allow me to look into it ?

Same problem here...

My persistence.xml file:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence">
    <persistence-unit name="portaltecnico" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.connection.driver_class" value="org.firebirdsql.jdbc.FBDriver"/>
            <property name="hibernate.connection.url" value="jdbc:firebirdsql:path2db"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.FirebirdDialect"/>
            <property name="hibernate.connection.username" value="user"/>
            <property name="hibernate.connection.password" value="pass"/>
        </properties>
    </persistence-unit>
</persistence>
